To convert kelvins to Celsius, subtract 273.15 from your kelvin temperature.
So, 286-273.15 is 12.85.
The average global temperature in Celsius is 12.85 degrees Celsius.

Answer:
d = 7.9 g/mL
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of brown metal = 14.2 g
Volume = 1.8 mL
Density = ?
Solution:
d = m/v
d = 14.2 g/1.8 mL
d = 7.9 g/mL
Answer: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon.
Explanation:
One mole of any element has a mass in grams that is equal to its atomic number, and has exactly 6.02 x 1023 atoms however because the atoms of each element have different sizes and weights, then the volume that each one occupies is different.
